Black, 1-part, room temperature vulcanizing acetoxy silicone paste sealant.
LOCTITE® SI 5940 is a black, 1-part, room temperature vulcanizing acetoxy silicone paste sealant. It is primarily used as a general-purpose sealing and bonding agent, space-filling rubber adhesive or formed-in-place gasket. It adheres to clean metal, glass, most non-oily woods, silicone resin, vulcanized silicone rubber, ceramic, natural and synthetic fibre and many painted and plastic surfaces.
Excellent resistance to ageing, shrinkage, cracking and discoloring.
Cures on exposure to moisture in the air to form a tough, flexible, waterproof, oil-resistant silicone rubber bond.
Typically used in applications with an operating range of -50°C to +200°C and can intermittently reach temperatures up to +220°C.
